Write the definition of a function named printpoweroftwostars that receives a non-negative integer n and prints a line consistin

g of "2 to the n" asterisks. so, if the function received 4 it would print 2 to the 4 asterisks, that is, 16 asterisks: **************** and if it received 0 it would print 2 to the 0 (i.e. 1) asterisks: * the function must not use a loop of any kind (for, while, do-while) to accomplish its job

To accomplish this without using a loop,
we can use math on a string.

Example:
print("apple" * 8)

Output:
appleappleappleappleappleappleappleapple

In this example,
the multiplication by 8 actually creates 8 copies of the string.

So that's the type of logic we want to apply to our problem.

<span>def powersOfTwo(number):
if number >= 0:
return print("*" * 2**number)
else:
<span>return

Hmm I can't make indentations in this box,
so it's doesn't format correctly.
Hopefully you get the idea though.

We're taking the string containing an asterisk and copying it 2^(number) times.

Beyond that you will need to call the function below.
Test it with some different values.

powersOfTwo(4) should print 2^4 asterisks: ****************</span></span>

Which password attack method uses long lists of words that have been predefined and can be quickly downloaded for use to break a
vova2212 [387]

Answer:

A dictonary attack.

Explanation:

Dictionaries hold many words that can be downloaded and used. Word or name passwords are usually just one word or maybe two. In other words, predefined words being used as a password? Not safe. When someone attempts to crack it, they use brute force attacks. Among these are dictionary attacks, which focus on the actual words rather than numbers.

Answer the following questions:
victus00 [196]

Answer:

The answer to the following questions can be given as:

Question: 1

value of foo is = 1020

Question: 2

Output of the code is = false

Question: 3

function add(a, b)

{

 return a && b ? a + b : function (c) { return a + c; };

}

var a=add(2,5);

var x=add(2)(5);

print(a);

print(x);

output:  

7

7

Question: 4

"goh angasal a m'i"

Question: 5

In this we check that if in the window a foo function exists. otherwise we set windows.foo to bar.

Question: 6

first alert shows the value "Hello World";

second alert shows value ReferenceError, In this bar not defined.

Question: 7

The value of foo.length is  2

Question: 8

The value of foo.x is undefined

Question: 9

Function print = "one", "three", "two" .

Question :10

It is difficult to define because doSomethingElse() function is not defined.

Explanation:

In question 1 the value of the foo variable is 1020 because we perform the string concat operation.

In question 2 Output of the code is false because float value keeps in binary and when we convert 0.1 or 0.2 to binary so it is not the same.

In question 3 the output of both functions is 7.

In question 4 the output is goh angasal a m'i because In this code we use the reverse() function, split() function and join() function. Reverse function reverses the value. split function splits the value and join function join all the value of the string in a line.

In question 5 we check the value.

In question 6, the first output is Hello World and second is ReferenceError.

In question 7, the value of foo.length is 2 because this foo array we insert only 2 values.

In question 8, the value of foo.x is undefined because in the variable we reset the value of foo all together, so foo.x value is undefined.

In the question 9 function print "one",  

"three",  

"two" because In the function first, we print the message that is "one" then we define a function in this function we print the value  

"two" but before creating object we call the "three" so the print value is "one",  

"three",  

"two".

In question 10 function, the output of this function is undefined.
